Trench Foot

Trench Foot

Trench foot (immersion foot) is a cold injury that occurs gradually
over several days of exposure to cold, but not freezing, temperatures. The name
comes from World War I troops who developed symptoms after standing in cold,
wet trenches.

Signs and symptoms of trench foot include:

Red skin that turns pale and
swollen.

Numbness or burning pain.

Leg
cramps.

No actual freezing of the skin.

A slow or
absent pulse in the foot.

Development of blisters or ulcers after 2
to 7 days.

First aid for trench foot includes rewarming the affected areas,
relieving pain, and preventing problems such as infection or dead skin
(gangrene).
